Specification of Letters Patent. Application filed March 1a, 1908. serial a... 421,943.

Patented Sept. 22, 1908.

To all whom it may concern:

Be it known that I, HENRY W. MAURER, of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Devices for Attach- .1 panying drawin s, forming a part of this specification, an to the reference-numerals marked thereon.

The present invention relates to devices for attaching thermometers projects into the vat or tank, and has the thermometer detachably secured thereto in order that the latter may be removed and.

applied to socket pieces of other vats or tanks. v

An object of the present invention is to, form the socket piece in such a manner that all sharp corners or crevices will be eliminated so that particles cannot collect therein,

when the vat is used for making beer or producing anyother food roducts.

To this and other en s the invention consists in certain improvements and combina-. tions of parts all as will be hereinafter more fully described, the novel features being 7 pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a side view of the thermometer Socket piece, and Fig. 2 is a longitudinal sectional view of the socket piece applied to a vat-wall and having the thermometer secured thereto. Referring more particularly to the drawings 1 indicates a. vat wall having a perforation 2which receives the threaded ortion 3 of the socket iece. The socket iece comprises preferaiily a-cylindrical ho low bod portion 4 havin' formed thereon the threa ed portion 3 an an annular flange or shoulder 5 at the inner end of the threaded portion. Extending from one end of the body I portion is a reduced hollow extension 6 com municating with the hollow body portion,

closed at its" outer end and having an inner wall tapering toward its'outer end, a beveled portion 7 being formed at the inner end of the wall.

When the socket iece is fitted in a pere shoulder 5 abuts a to tanks, vats 15 or the like of the type in which a socket piece tension 13 into the result being very desirablepacking ring 8 that is covered with soft metal 9 in order to protect the rin against the contents of the tank. It is hel against the packing ring by a nut 10 that cooperates with the threaded portion of the socket iece arranged on the exterior of the tan a washer 11 being interposed between the nut and the tank.

The thermometer 12 may be of any suitable construction and have atapering extension 13 inclosing the usual thermometer tube to fit within and contact with the inner wall of the tapering extension 6 of the socket piece, the beveled portion 7 serving to guide theexextension 6. The body portion 4 contains the usual large portion 14 of the thermometer, on which may be journaled an internally threaded nut 15, that cooperates with the projecting part of the threads on the threaded portion 3 of the socket piece. exterior Wall of the extension 13 into firm contact with the inner wall of the extension 6 the thermometer through the extension 131 The socket iece is made of one piece-of material and t e corners between the several portions thereof are curved so that no crevlces are provided to collect material. The one set of threads serves for securing it to the tank and for holding the thermometer thereto.

A device constructed in accordance with- .this invention is inexpensive to manufacture and to install. It is sanitary in every respect and is thus adapted'for use in beer making and in the production of food products. claim as my invention:
